Task id16465

A piece of ice weighing mL = 50 g, taken at a temperature tL = -10°C, is dropped into a brass calorimeter with a mass of mL = 200 g, containing a mass of MW = 0.5 kg of water at a temperature tW = 20°C. Find the temperature Q of the water in the calorimeter after the ice melts. Specific heat capacity of water sl = 4.19 kJ/(kg K), ice sl = 2.1 kJ/(kg K), brass slat = 0.38 kJ/(kg K); specific heat of melting of ice L = 0.33 MJ/kg.
